“…Later, lowmelting sulfophosphate glasses (T g b 400°C) received considerable attention as lead-free candidate for sealing applications, polymer coforming [4][5][6] and recently for infiltration of various types of preforms [7,8]. Sulfur is mainly incorporated into sulfophosphate glasses as isolated SO 4 2− groups [9], whereby replacing P 2 O 5 with SO 3 results in a progressive depolymerization of the phosphate network, i.e. increase of the ionic character.…”

“…Li 2 SO 4 addition increased charge carrier concentration that was reported to migrate through vacancy mechanism leading to enhancement in conductivity [63]. Another report suggests that the higher SO − groups [65] or sulfate groups are not incorporated into phosphorus-oxygen chains of the initial glass but form an independent sulfur-oxygen network [66]. Even it is hypothesized that sulfur can occupy five different structural positions in sulfate-polyphosphate chains [67] (Figure 9).…”

Glassy electrolytes could be a potential candidate for all-solid-state batteries that are considered new-generation energy storage devices. As glasses are one of the potential fast ion-conducting electrolytes, progressive advances in glassy electrolytes have been undergoing to get commercial attention. However, the challenges offered by ionic conductivity at room temperature (10 −5 -10 −3 S•cm −1 ) in comparison to those of organic liquid electrolytes (10 −2 S•cm −1 ) hindered the applicability of such electrolytes. To enhance the research development on ionic conductivity, the overall picture of the ionic conductivity of glassy electrolytes is reviewed in this article with a focus on alkali oxide and sulfide glasses. We portray here the techniques applied for alkali ion conductivity enhancement, such as methods of glass preparation, host optimization, doping, and salt addition for enhancing alkali ionic conductivity in the glasses.

“…Low-melting sulfophosphate glasses were introduced for the first time by Mamoshin and co-workers in the 1980s [4][5][6]. The Fourier transformed infrared (FTIR) spectra of the Na 2 SO 4 -NaPO 3 glass revealed the formation of separate sulfur-oxygen network in the sulfate groups, which are unbound to polyphosphate chains [6]. The possibility of the formation of a mixed sulfate phosphate has been approved by the NMR spectroscopy of Li 2 SO 4 -Li 2 O-P 2 O 5 and Na 2 SO 4 -P 2 O 5 -H 2 O glass systems [7,8].…”

Samarium (Sm 3+) doped magnesium zinc sulfophosphate glass system of composition (60-x)P 2 O 5-20MgO-20ZnSO 4-xSm 2 O 3 (x = 0.0, 0.5, 1.0, 1.5 and 2.0 mol%) were synthesized using melt-quenching technique. The structure and physical properties of prepared glass samples were characterized. The X-ray diffraction pattern verified their amorphous nature. The physical properties such as density, refractive index, molar volume, rare earth ion concentration, etc. were calculated. The decrease in the optical bandgap energy with increasing Sm 2 O 3 contents was attributed to the alteration in the glass network structures. Fourier transformed infrared spectra and Raman analyses manifested the depolymerization of ZnSO 4 in the phosphate host matrix. The present findings may be beneficial for the advancement of functional glasses.
